Problems solved by technology

[0004] However, for 4G and 5G interoperability between different systems, if the traditional connection interoperability mechanism is used, the terminal will measure all 5G neighboring cells, and when the measurement reporting conditions are met, the terminal may switch to the 5G neighboring cell. After switching to a 5G cell, the terminal works abnormally because the terminal cannot process the 5G signaling issued by the 5G cell

Abstract

The invention discloses a connection management method, a first network device, a terminal device and a system. The connection management method comprises the following steps: obtaining capability information of at least one adjacent cell; obtaining the capability information of a terminal device in the service cell managed by the terminal device; selecting at least one adjacent cell to be measured for the terminal device based on the capability information of the terminal device and the capability information of the at least one adjacent cell; and confirming a target cell to which the terminal device switches in the at least one adjacent cell to be measured or confirming to configure dual connections for the terminal device based on the measurement report reported by the terminal device for the at least one adjacent cell to be measured; wherein the dual connections indicate that the terminal device establishes connections with the service cell and the target cell.

Description

Technical field [0001] The present invention relates to information acquisition technology in the communication field, and in particular to a connection management method, a first network device, a terminal device and a system. Background technique [0002] 5G can be seen as a further evolution after LTE, that is, evolution also introduces innovative new technologies. At present, 3GPP has defined two schemes for 5G New Radio (NR) networking, which are independent networking (Standalone, SA) and non-standalone networking (Non-Standalone, NSA). Among them, non-independent networking means that 4G independently deploys the control plane (4G bearer control signaling), 5G and 4G jointly deploy the user plane (5G and 4G bear user plane data) or 5G independently deploys the user plane (only 5G bearer user plane) Data); independent networking refers to 5G independent deployment of the control plane and user plane (5G independent bearer control signaling and user plane data), the indepen...
